8 Useful Benefits of Plastic Injection Molding

The plastic injection molding method is one of the most used techniques for producing a high volume of plastic parts. This method relies on a heated barrel and a special mold cavity to create the precise shape and size of different plastic objects. Here are a few of the benefits of using plastic injection molding:

Accurate

Plastic injection molding is a highly accurate method that can easily shape virtually any part. In most cases, the accuracy level of this method is within 0.005 inches.

Flexibility

The production process is extremely flexible with the option to make adjustments to match the needs. For instance, it is easy to change the color of the product in production and even change the type of material in use.

High strength components

This manufacturing process is a perfect option for creating high strength components. It is possible to inject a preferred type of filler into the plastic at the molding stage to enhance the all-round strength and reduce the density of the liquid plastic. This technique is highly favored in industries that need to mold the strongest parts possible.

Fast

This is often the favored method for longer production runs because it is very fast at shaping the individual parts. Even though the complexity of the desired shape can impact the time, most parts are easily completed within a time-frame of 15 to 30 seconds.

Labor

Injection molding is a highly automated process that is self-gating and built with a streamlined operation in mind. It needs minimal supervision once the initial shaping information has been entered. This means there is a great opportunity to save on labor costs for the most efficient production line.

Smooth finish

Any part that is molded using this technique needs no extra finishing at the end. The actual mold is designed to produce a part that fully resembles its finish appearance, and no extra work is needed to make it smooth or remove rough edges.

Resourceful

This is a production method that leads to minimal waste and can benefit the environment. A useful feature is the ability to only use the exact amount of plastic to create the part. Also, in the event of having any leftover plastic, this is easy to recycle after use.

Low-cost production

In the long-term, plastic injection molding is one of the most cost-effective production methods, and a lot cheaper than alternatives like plastic machining. The actual process of creating the mold is the most expensive part, but the long runs are significantly more favorable in cost.
